SASH-FASTENER.

SPECIFICATION forming part of Letter s Patent No. 322,426l dated July 21, 1885.

Application filed June 9, 1884. (No model.)

To all whom it may concern,.-

.Be it known that I, WINEIELDS. CUNNING- HAM, of the city of Springfield, county of Clark, and State of Ohio, have invented certain new and useful Improvements in Win- 4dow-Fastenings, of which the following is a specification.

This invention relates to sash-fasteners, and is especially intended as an improvement npon that class wherein the locking-bolts extend out at right angles to one another to adapt them to engage with the sash and windowframe, thereby locking the sashes together and at the same time locking them to the window-frame;

My invention consists in the construction of a sash-fastener substantially as hereinafter described.

Figure l represents a sectional plan View of a window-faste11ing constructed in accordance with my invention, the bolts being shown as extending into and looking with the sash and window-frame, Fig. 2, a plan view of the same; Fig. 3, a vertical section on dotted line x x,

Fig. l; Fig. 4, a perspective View in detail of the locking bolts; and Fig. 5 represents a screw-threaded thimble to receive the bolts.

The casing A, which will be of any suitable material, is screwed to the inside sash of a window at, preferably', the right-hand corner of the meeting-rail B. The said casing is provided with guiding-slots for the reception of locking-bolts C C, the said locking-bolts being overlapped and sliding at right angles to one another. The sliding bolts C C are provided with teethD D', said teeth being adapted to mesh with the teeth of a pinion, E, which pinion is provided with a shaft, F, that extends out through the casing and is connected to a hinged lever, G, said lever G being adapted to turn the pinion to throw the bolts out or in, as desired. The pinion E will pref-V erably be provided with teeth only a portion of its circumference, and will be provided with a projection, I-I; at its lower side to bear against the locking-bolts, to,keep them from b'eing accidentally displaced.

In practice the sash B and frame B2 of the windcw` into which the bolts are to extend will be provided with a thimble, I, which is f let into the wood as shown in the drawings.

In operating my improved window-fastening, the bolts being normally drawn in, the lever G will be moved until its hinged end engages with the stop .I on thecasing A, which will revolve the pinion E and slidethe bolts which mesh therewith out into the sash B and frame B2, thereby locking the sashes and frame together.

As will be noticed, the upper sash, B', may be lowered and locked at any desired position.

The thimble I is provided with a collar, I',

and is screw-threaded at its shank. A slot,

l2, is formed in the lower end of the shank, said slot permitting a screw-driver to beinserted to screw the thimble into the wood. This forms a strong and simple bearing for the ends of the bolts.

I claim The combination, in a sash-fastener provided with a casing of the shape herein shown, of the bolts C C', adapted to slide over -one another, as described, and the toothed pinion E, provided with the projecting flange H to bear upon the bolts C C', to prevent displacement, and the hinged lever G to operate the bolts, all constructed and operating substantially as shown and described.
